  1. Glock MOS fixed sight set.

    Posted by Robert Raby on Feb 5th 2019

    Installed on my Gen 4 G17MOS Fastfire III. Perfect co-witness. Like the all black.

  2. Perfect for Glock MOS and Vortex Venom

    These are the perfect sights for your Glock MOS with Vortex Venom red dot. They co-witness perfectly. I chose the all black over the fiber optic front to reduce the opportunity for confusion of 2 dots. Despite being skeptical about the all black sights, I am very happy with them and they are working out great as back up sights. I installed the sights on a Glock 17 Gen 5 MOS and they are perfect. You will have to file down the rear sight a bit, but you will get a great fit when you are done. Best option for back ups to your Venom.

  3. Perfection for Glock G40 MOS

    Installed the sights on a Glock G40 MOS 10mm. Also used in conjunction with a Vortex Viper. Sights are the perfect height to Lower 1/3 co witness with the viper. Rear sight is thick, so with the Viper you will have to modify the Vipers rubber sight cover to fit between the Viper and rear sight. Easy install with tools provided. Sights are top quality! Great folks to deal with!

  4. Glock 19 MOS Vortex Venom Perfect Match!!

    This is the way to go if you are looking for the red dot to sit just on top of the front sight post. Great products and customer service.
